Remote-control Tortoise
Q.
I would like to know if it is possible to have a Tortoise
switch motor be thrown from two separate locations by sepa-
rate DPDT switches, and if so, how would you wire it?

A.
This circuit acts like 3-way wall switches. Toggling either
switch will change the position of the turnout from where it was.
I can’t see any reason that you couldn’t extend this to as many
DPDT switches as you might desire. Here is a simple schematic
in .jpeg form (1). Not my idea of the best user interface, but
there you go.
The one big disadvantage for this approach is that the position
of the toggles doesn't tell you which way the turnout is thrown.
